Abstract: Disclosed here is an audio system and a method of operating the same. The audio system comprises a receiver module for receiving radio frequency (RF) input signal associated with a plurality of radio stations, an Analog to Digital Converter (ADC) coupled to the receiver for digitizing the received RF input signal and a stored set of computer-executable instructions. The instructions include those for selecting a particular radio station from the plurality of radio stations, shifting the frequency of the particular radio station to an intermediate frequency (IF), demodulating the frequency shifted portion of the RF input signal to retrieve an output signal and generating a time division multiplexed signal based on the output signal.

Abstract: Disclosed here are methods, systems, paradigms and structures for determining a reach of an audio program broadcast on a radio station. The method includes gathering one or more data logs associated with each of a subset of audio listeners, where a given data log includes a first indicia of the given audio program listened to by the given audio listener within a given time period. The method further includes identifying one or more audio program listeners from the subset of audio listeners who listened to the audio program broadcast on the radio station, the identification of a given audio program listener based on a match between a second indicia associated with the audio program and the first indicia of given audio program listened to by the given audio program listener.
